Hi there,

does anybody have any information if those latest Sony devices still only can handle a limited bandwidth over DLNA?

I've already got a 24EX320 and plan on adding a 40EX720. Testing on the 24EX320 isn't conclusive at the moment, as I'm kind of struggling to get my HDTV recordings into the library and displayed on the TV set at all.

Is there sth like a proper Bravia 2011 profile out there?

Have a nice one,
Low

there is a bravia profile as standard in serviio. use the drop down menu in the console to select it.

We've already found that the 2011 models may be able to play some more formats natively than previous models in another thread, and I'd like to keep transcoding action as low a possible. I think the profile itself is discussed in the beta forum as well. My main thing now is that if the Bravia 2011 can't handle higher bitrates than e.g. my otherwise trusted BDP S370 player, it's not worth going for the larger, more expensive tv set.

No, but 20/25Mbps is a DLNA limitation.

Could you explain?

Good question, we need 2011 users (not me) to provide such "good" profile.

Ok, recordings from HD DVB should be well below that. I put one of my files through bitrate viewer, and it had a peak at 15k.

Could you explain?

Yes, of course. I'm not quite through with what the tv lists but doesn't play or doesn't list at all. I'd very much like to trick it into playing my HDTV recordings, which come as mkv files with 50fps h264 video and potentially multiple audio in ac3 and mp2. I could omit all audio but ac3, if it helped. In ffmpeg such a file presents as follows:

Code:: [h264 @ 02b31730] mmco: unref short failure [h264 @ 02b31730] number of reference frames exceeds max (probably corrupt input), discarding one [matroska,webm @ 012ed150] Estimating duration from bitrate, this may be inaccurate Seems stream 0 codec frame rate differs from container frame rate: 100.00 (100/1) -> 50.17 (301/6) Input #0, matroska,webm, from 'G:\path\to\my\files\HDTV\Sherlock-remux.mkv': Duration: 01:27:59.84, start: 0.000000, bitrate: 704 kb/s Stream #0.0: Video: h264, yuv420p, 1280x720 [PAR 1:1 DAR 16:9], 50 fps, 50.17 tbr, 1k tbn, 100 tbc Stream #0.1(ger): Audio: ac3, 48000 Hz, 5.1, s16, 448 kb/s Stream #0.2(ger): Audio: mp2, 48000 Hz, 2 channels, s16, 256 kb/s At least one output file must be specified

SD mkv with h264/ac3 play quite well as discussed in the Bravia 2011 thread. EDIT: I just found that the same elementary streams remuxed as a TS play fine, even with multiple audio tracks. Hmmm, I think I need to dig a bit further into that, as my (so far) trusted BDP S370 is fine with the mkv, but not with the TS (no audio).

we need 2011 users (not me) to provide such "good" profile.

The Bravia 2011 thread pretty often refers to Serviio 0.6 and points out that there is work already going on in 0.6. Which tells me that I may not be worthwile putting effort in creating a profile while still on 0.5.2. Looking forward to trying 0.6, as I'll soon have two Bravias to feed.

I'll check back frequently and take notes about the capabilites of my system on the way.

I posted about 0.6 at the of the 11 pages, it should have been in the beta forum. While it has a profile for Sony its not working right for AVI's as yet, details of this are in the beta forum and other postings as I'm testing files etc

It will hopefully get sorted for the public release but currently its no different that using 0.52

nx3,

Unfortunately I have no access to the beta forum. What I [i]do[/i] have is some files which do or don't play on both of my Bravias and I don't have a clue why. Those are hdtv recordings (from the same station), and all but one of them show a very jerky playback. It's not just stuttering, the frames are jumping back and forth. The only file that does play so far has a pretty high bitrate overall, so high bandwidth alone should not lead the Bravia into jerking around frames. And it's not a wired/wireless issue either. The files in question do not list from USB, so I couldn't test local playback.

Yes, I could provide examples if sb was interested. I tried remuxing ts to mkv and vice versa, as well as remuxing to single audio track. No change.

(I have a similar effect with sd stuff (avc/ac3/mkv), where the jerkiness disappears after a few seconds, but it doesn't disappear in hd.)

Have a nice one,
Low

.

Could you check to detailed logging file when you start the file? Look at the ffmpeg command line used.
Not sure the 50fps is supported by Sony Bravia TV.
Probably the frame rate must be clipped and forced to 24fps, 25fps or 30 fps...

Illico,

thank you so much for making me dig into log files 'n stuff deep enough to discover that...

a) all the HDTV files in hand are correctly advertised as AVC_TS_HD_24_AC3_ISO
b) none of them gets transcoded, therefore there is no ffmpeg command line spawned I'm afraid.
c) the files that don't play properly show numerous "invalid timestamps" errors when analyzed with ffmpeg -i, which I had not at all noticed before.

All files showing "invalid timestamps" errors are those I had remuxed with TSmuxeR somewhere in the process of editing. :oops:

Bah!

The "good" files are those which I had just cut and re-saved with DVR-Studio HD (brilliant piece of software btw). They - so far - play flawlessly on the Bravia without transcoding. And if they are not transcoded, they still should be 50 fps, right? If so, there is a brilliantly short chain of just cutting the original HDTV dvb recording right onto the Serviio machine and streaming it natively to the Bravia.

I played around with various flags/options in TSmuxeR and didn't get a single file that had no "invalid timestamps" errors. Seems I have to look for another muxer to mux additional languages into existing TS files. :cry:

Thanks again,
Low
